Title: Subscriber station for telephone systems
IPC: H04M9/00
Filed: 1974-12-09
Abstract: 1490869 Substation circuits WESTERN ELECTRIC CO Inc 9 Dec 1974 [12 Dec 1973] 53237/74 Heading H4K A key telephone substation includes a relay which is normally short-circuited but which is permitted to operate in series with the loop through the subset transducer circuitry and then hold via one of its own contacts when a line-hold key is operated. Any one of the stations, e.g. S1, connected to an exchange line, e.g. L1, may respond to ringing by going off-hook, thereby closing his hook switch contacts SH and operating his line key so as to place the contacts 1PU in their rest condition. Consequently the light indicators LED-1 in each station glow continuously. If the responding station, e.g. S1, wishes to have a private conversation in his office or to communicate over another line he presses his hold key thereby opening contact 1H-1 and thus removing a short-circuit from relay 1B. The latter operates in series with the subset transducer circuitry and then holds via its make contact 1B-1. The line L1 is thus terminated via a suitable impedance and the substation circuit is short-circuited. If the station goes on-hook or operates his line key thus opening contacts 1SH or transferring the 1PU contacts to their make side, the line remains held with the lamps LED glowing. If any station wishes to break-in by going off-hook and operating his line key, i.e. contacts 2PU or 3PU in their rest state, or, if the original station releases his hold key, the holding relay 1B is once more short-circuited and thus falls back to release the hold condition.

Title: Improvements in or relating to the removal of ruthenium from solutions
Inventor: AUCHAPT JACQUELINE
IPC: G21F9/10
Filed: 1965-12-17
Abstract: Ruthenium, strontium, calcium, cerium, zirconium and niobium are removed from a solution by adjusting the pH to not more than 2, adding periodate and/or paraperiodate ions, agitating, and adding lead ions at a tempaerture and pH so as to form a precipitate of lead periodate and/or paraperiodate entraining the ruthenium.  Preferably the concentration of periodate ions is about 200 p.p.m., the temperature is about 0 DEG  C., and precipitation is effected by raising the pH to about 5.  The periodate ions may be added as periodic acid or its sodium or potassium salts, or as sodium paraperiodate.  The process may be used in the decontamination of effluents from the treatment of irradiated nuclear fuels.  These effluents are first rendered oxidative by adding potassium permanganate or sodium hypochlorite solution. Other decontamination processes which may be used in conjunction with the process according to the invention are (a) removal of ruthenium in cationic form by entrainment with ferrous hydroxide, (b) removal of caesium by addition of potassium ferrocyanide and nickel ions, (c) removal of strontium by entrainment with calcium carbonate.

Abstract: 1,208,449. Lasers. COMPAGNIE GENEBALE D'ELECTRICITE. 12 Dec., 1967 [15 Dec., 1966; 5 June, 1967], No. 56316/67. Headings H1C. [Also in Division G1] A reference plane on a rotating body is determined by mounting a laser gyrometer so that the flow of the body's rotation vector through the plane of the gyrometer varies with the angle of the gyrometer about its axis and measuring the output frequency of the gyrometer and means for indicating the position of the gyrometer plane yielding a preselected output frequency. For determining a direction relative to the terrestrial rotation vector, gyrometer 11 is rotated about the axis X-X<SP>1</SP> by a motor 17 and its output is taken from slip-ring 21 to a frequency discriminator 22 and a bandpass filter 23 centred on the rest frequency of the gyrometer. A laser 12 produces pulses in a detector 13 twice per revolution and these pulses operate a chopper 25 to invert the signal from filter 23 which is smoothed and applied to a meter 30. It is shown that meter 30 indicates zero when detector 13 is in a north position, so north may be determined by adjusting the detector until meter 30 reads zero. The adjustment may be by servo loop 27, 15, 16. In a modification, Fig. 3 (not shown), the gyrometer has a two-bearing inclined mounting on a block which also supports sighting device replacing detector 13 and the servomotor rotates the whole block. The laser is replaced by a mirror. The position of the gyrometer relative to the shaft may be adjusted for setting-up. The invention may be mounted on an artificial satellite.
